Quiet bedroom comfort across CEC Climate Zone 9 (Studio City)
Sleep cooling is a measurable outcome, not a vague preference. The targets in Studio City bedrooms: nighttime temperature swing under 4°F, noise floor under 30 dBA at the bed (ASHRAE NC 25–30 sleeping room target), supply airflow direction parallel to the bed long axis, indoor RH 45–55%, and return path that does not pinch when the door closes.
Bedroom comfort should be designed around sound, airflow direction, and nighttime runtime, not just capacity.
Hillside lots on the north slope of the Santa Monica Mountains receive dramatic afternoon sun load on south-facing facades; solar gain dominates AC sizing more than ambient temperature
